Description

Technical Field

[0001] The present application relates to the technical field of wheel hub forging, and in particular to a modular cooling system for manufacturing forged wheel hubs. Background Art

[0002] Currently in the wheel hub industry, there are many manufacturing methods for wheels, such as casting, forging, and spinning. Among them, forged wheels are particularly valued by the wheel hub industry because of their light weight and high strength. Forged wheels are a process in which preheated aluminum ingots are placed on a mold and forged multiple times to finally form a wheel hub.

[0003] After multiple forgings, the heat on the mold is relatively high and needs to be cooled. However, the heat generation locations on the actual area of ​​the wheel hub are different. For example, the temperature may be high in some parts of the mold. The current cooling method is indiscriminate cooling, which causes the temperature in some parts to be still high. In the long run, it will affect the cooling effect and the life of the mold itself. Summary of the invention

[0004] In order to be able to adjust the cooling effect of the mold according to actual conditions, the present application provides a modular cooling system for forged wheel hub manufacturing.

[0005] The present application provides a modular cooling system for manufacturing forged wheels, which adopts the following technical solution: a modular cooling system for manufacturing forged wheels, comprising a mold, wherein the bottom of the mold has a first cooling unit, wherein the first cooling unit comprises a cooling channel fixed to the bottom of the mold, a cooling column arranged in the cooling channel and distributed in an array at the bottom of the mold, wherein the outer wall of the cooling column is provided with a plurality of cooling fins; The lower side of the first cooling unit is detachably connected to a second cooling unit, and the cooling column has a liquid cooling channel extending along the axial direction. When the second cooling unit is plugged in, the corresponding liquid cooling channel of the cooling column is connected.

[0006] By adopting the above technical solution, under normal circumstances, cooling is performed through the first cooling unit, which works by introducing continuous cooling air into the cooling channel, and continuously taking away the heat from the cooling column through the cooling fins. When the heat is too high at a local position, a second cooling unit is inserted into the cooling column at the corresponding position. Coolant circulates in the second cooling unit, which can take away the heat in the cooling column at the corresponding position more quickly through the cooling channel, thereby achieving a local strong cooling effect.

[0007] Preferably, the liquid cooling channel is spirally wrapped around the cooling column.

[0008] Preferably, the end of the cooling column has two connecting channels connected to the liquid cooling channel, and the second cooling unit has two inserting tubes respectively inserted into the connecting channels.

[0009] Preferably, the end of the connecting channel is located outside the cooling channel.

[0010] Preferably, a limiting protrusion is provided on the connecting channel for radial sliding, and the outer wall of the insert tube has a limiting ring groove for the limiting protrusion to be embedded in, and a plurality of the limiting protrusions are evenly distributed along the circumferential direction.

[0011] Preferably, a sealing protrusion is further provided on the connecting channel along the axial direction, and the outer wall of the insert tube has a sealing ring groove for the sealing protrusion to be embedded.

[0012] Preferably, the outer wall of the connecting channel is threadedly connected with a contact cylinder, the outward end of the sealing protrusion has a first contact ball for contacting the inner wall of the contact cylinder, and the inner wall of the end of the contact cylinder close to the sealing protrusion has a contact slope.

[0013] Preferably, an annular airbag is embedded in the sealing ring groove, the outer side of the annular airbag is flush with the edge of the sealing ring groove, and the end of the sealing protrusion has a convex point for abutting against the annular airbag.

[0014] In summary, the present application includes at least one of the following beneficial technical effects: 1. Cooling is performed through the first cooling unit. Its working mode is to introduce continuous cooling air into the cooling channel, and continuously take away the heat from the cooling column through the cooling fins. When the heat is too high at a local position, the second cooling unit is inserted into the cooling column at the corresponding position. There is coolant circulating in the second cooling unit, which can take away the heat from the cooling column at the corresponding position faster through the cooling channel, so as to achieve the effect of local strong cooling. 2. After the insertion of the cannula, the movement of the contact tube can make the limit protrusion to limit the axial direction, and at the same time, the sealing protrusion will be inserted into the sealing ring groove. After the protrusion contacts the annular airbag, the sealing effect is achieved. At the same time, during the opening process, the annular airbag can help reset. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The present application is further described in detail below in conjunction with the accompanying drawings.

[0018] The present application embodiment discloses a modular cooling system for manufacturing a forged wheel hub, referring to Figure 1 , Figure 2 , including a mold 100, the bottom of the mold 100 has a first cooling unit, the first cooling unit includes a cooling channel 111 fixed to the bottom of the mold 100, cooling columns 112 arranged in the cooling channel 111 and distributed in an array at the bottom of the mold 100, and a plurality of cooling fins 113 are arranged on the outer wall of the cooling column 112. In a conventional heat dissipation method, cooling air is blown from one end of the cooling channel 111, and the cooling fins 113 can take away the heat when interacting with the gas to achieve the effect of cooling and lowering the temperature.

[0019] In order to strongly cool down some areas, the lower side of the first cooling unit is detachably connected to the second cooling unit 114, and the cooling column 112 has a liquid cooling channel 115 extending along the axial direction. When the second cooling unit 114 is plugged in, the liquid cooling channel 115 of the corresponding cooling column 112 is connected. In this embodiment, a circulating coolant is introduced into the second cooling unit 114, and the heat on the cooling column 112 can be circulated and taken away along the liquid cooling channel 115, so that the parts with higher temperatures can be more effectively dissipated. In order to facilitate improving the heat dissipation effect, the cooling channel 111 in this embodiment is spirally wrapped around the cooling column 112.

[0020] The end of the cooling column 112 has two connecting channels 120 connected to the liquid cooling channel 115. The end of the connecting channel 120 is located outside the cooling channel 111. When the second cooling unit 114 is not connected, it will not affect the cooling effect of the cooling channel 111. The second cooling unit 114 has two inserts 121 respectively inserted into the connecting channel 120.

[0021] Reference Figure 2 , Figure 3A sealing ring groove 122 and a limiting ring groove 123 are respectively provided on the outer wall of the insert tube 121 along the axial direction. The sealing ring groove 122 is closer to the first cooling unit. At the same time, a limiting protrusion 125 and a sealing protrusion 124 are provided along the radial sliding arrangement on the connecting channel 120. There are a number of sealing protrusions 124 evenly distributed along the circumferential direction, and the sealing protrusion 124 is connected to the limiting protrusion 125 through an axially extending connecting rod 127. At the same time, a first contact ball 126 is provided at the outward end of the sealing protrusion 124. In this embodiment, a contact cylinder 130 is threadedly connected to the outer wall of the connecting channel 120. During the rotation process, the contact cylinder 130 will abut against the first contact ball 126, so that the sealing protrusion 124 and the limiting protrusion 125 move inward synchronously.

[0022] In order to facilitate the contact between the contact cylinder 130 and the first contact ball 126, a contact slope 131 is provided on the inner wall of the end of the contact cylinder 130. During the spiral movement, the inner wall of the contact cylinder 130 abuts against the first contact ball 126, so that the limiting protrusion 125 and the sealing protrusion 124 move inward synchronously, and the limiting protrusion 125 serves as a limit in the axial direction, while the insert tube 121 and the connecting channel 120 serve as limit in the radial direction.

[0023] In this embodiment, an annular airbag 140 is embedded in the sealing ring groove 122. The outer side of the annular airbag 140 is flush with the edge of the sealing ring groove 122. The end of the sealing protrusion 124 has a convex point 142 for contacting the annular airbag 140. During the inward movement, the convex point 142 will contact the middle part of the annular airbag 140, so that the annular airbag 140 is deformed outward, the gap at the connection is blocked, and the sealing effect is achieved. When the contact cylinder 130 is retreated, the annular airbag 140 will rebound and play a role in resetting. In this embodiment, in order to enable the annular airbag 140 to be deformed, the gas content inside it is 80-90%.

[0024] Reference Figure 4 When the retreat is completed, the outer side of the annular airbag 140 just presses the sealing protrusion 124 out of the sealing ring groove 122, so that the cannula 121 and the connecting channel 120 can be separated.

[0025] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
